senses pressure not flow

what happens if the inspiratory value sticks open

the expiratory limb will exhaust through the inspiratory limb - the ETCO2 waveform will become elevated

what happens if the expiratory value sticks open

the inspired volume will not enter the ET but instead will by pass and exhaust through the expiratory limb.

Positive pressure relief valve vs negative pressure relief value

positive will allow gas to escape from the system to the operating room if pressure builds in the system




negative will allow gas from the O2 to enter if pressure becomes to negative



what happens if you tip the vaporizer

liquid vapor will get into the vaporizer chamber and the carrier flow will carry more agent to the patient

primary function of any free floating valve is to prevent gases from leaking out of the system.

to permit gas flow after you have made a connection such as plugging lines into the wall.


all or none valve you supply the energy (the connection) and it will work all or nothing depending on the connection.
